#' Report working directory and usethis/RStudio project

#' @description `proj_sitrep()` reports
#'   * current working directory
#'   * the active usethis project
#'   * the active RStudio Project
#'
#' @description Call this function if things seem weird and you're not sure
#'   what's wrong or how to fix it. Usually, all three of these should coincide
#'   (or be unset) and `proj_sitrep()` provides suggested commands for getting
#'   back to this happy state.
#'
#' @return A named list, with S3 class `sitrep` (for printing purposes),
#'   reporting current working directory, active usethis project, and active
#'   RStudio Project
